I have had a longnose hawkfish for about 6-7 months in a 10 gallon to grow him out. He did not go through any type of quarantine or medication before being put into the 10 gallon. I am going to be transferring my 10 gallon coral, inverts, and other fish (a sissortail goby) into a different tank. However the hawkfish I have always wanted to have in my big display tank. I was wondering since I have had this hawkfish in the 10 gallon for 6-7 months is it safe to transfer it to my big display tank without quarantine? If any one can help that would be greatly appreciated.
